Crystal growth and physical characterization of the semiorganic bis(thiourea) cadmium chloride

Growth and characterization of a new metal-organic crystal: Potassium thiourea iodide

Growth and characterization of a new metal-organic crystal: potassium thiourea bromide

Transparent single crystals of potassium dihydrogen phosphate (KDP) were grown by modified Sankaranarayanan–Ramasamy (SR) method. The band gap energy for the KDP crystals was calculated from optical transmission spectrum. The theoretical calculations to determine the optical constants of the material and a technique for photonic band gap tuning, which is essentially required to develop the optoelectronic devices, were determined using the optical studies. Further, the Vicker's micro hardness as well as parameters such as fracture toughness (Kc), brittleness index (B) and yield strength (σv) are presented.

Growth, theoretical and optical studies on potassium dihydrogen phosphate (KDP) single crystals by modified Sankaranarayanan–Ramasamy (mSR) method

Crystal growth and defects characterization of zinc tris (thiourea) sulfate: a novel metalorganic nonlinear optical crystal

Sodiump-nitrophenolate dihydrate (NPNa) is a new semiorganic nonlinear optical crystal. It has a deff of about 1.2 times that of potassium titanyl phosphate. Large single crystals of NPNa were grown from water and methanol solutions by isothermal solvent evaporation. The morphology of the grown crystals was indexed. The defect content of the methanol grown crystals was evaluated by chemical etching and synchrotron topography. The section topography carried out on a large uncut crystal revealed a considerable reduction in the defect density away from the seed. The improved optical transmission of NPNa crystals was achieved by purifying the starting materials. The mechanical hardness of the NPNa crystals in the 010 plane was evaluated by Vickers and Knoop indentations.
